Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
It looks like this error is stemming from the Animentor – Lottie & Bodymovin widget for Elementor plugin that is causing the following error on the page which is affecting the execution of JS:
frontend.js?ver=1.0.0:144 Uncaught ReferenceError: elementorFrontend is not defined

I can suggest that you reach out to the author of this plugin so that they can help to fix this.
Looking forward to helping you. Thank you.
